FISH-EGG-HATC'HING TROUGH.

SPECIFICATION-forming part of Letters PatentNo. 277,805, dated May 15, 1883.

' Application tiled March 26, 18.83. (No model.)

lTo all whom it may concern:

Be it known that I, LIVINGSTON STONE, of Charlestown, in the county of Sullivan,of the State of New Hampshire, have invented a new and useful Improvement in Fish-Egg- Hatching Troughs; and I do hereby declare the same to be'described in the following speci# ication and represented in the accompanying drawings, ot' which- Figure l is a top View, Fig.'2 .a side elevation, Fig. 3 an end view, Fig. 4 a longitudinal section, Fig. 5 a transverse section, and Fig. 6 abottom view, of a hatching-trough embodying my invention, the nature of such invention being defined in the claim hereinafter presented.

The said hatching-trough is analogous to the well-known Villiamson hatching-trough, but differs from it in construction, whereby it can be readily taken apart and i'olded into a smaller compass for package or transportation. Instead of having sides and bottom made ot'` solid wood, such in my limproved trough are composed., ot'. a light water-.proof fabric or cloth stretched and laid and fastened on longitudinal'bars connecting the wooden nds and partitions ofthe trough, and confined thereto by means of' cleats and screws, as represented. 'Ihe employment ol" the light water prootI fabric or cloth tor the sides and bottom of the trough, and having the parts supporting such cloth or fabric constructed and adapted so as easily to be taken apart and connected together and to it, are material elem ents in my invention or improvement, and which render the trough ot' much value, and very advantageous iu several respects, in comparison with various well-known kinds ot' fish-egghatching troughs in use.

In the drawings, A and B denote the two ends ofthe trough, each ot' which is a rectangular piece ot'board notched at its four cori ners, as shown at a, to receive iush with its edges four connecting-bars, O O and D D.

Arranged between the two ends A B, and

at suitable distances apart, is a series of partitions, E F F, each ot which, like the said ends, is notched at its corners to receive the four connecting-bars C O and D D. The partition E has an arched notch or passage, b, extendingthrough it from its lower edge upward a suitable distance. Each partition F, has a passage, c, leading down through it, and open laterally at top and bottom, as shown at d and c.

The water-proof cloth or fabric to constitute the sides and bottom of the trough is shown at G, it being carried around the four connecting-bars O O and D D iu manner as shown in Fig. 5, and fastened to their upper edges and to the side and bottom edges ot' the end pieces and partitions by a series ot' cleats,v H, laid `upon it in manner as represented, and fastened to itand the said bars, end pieces, and partitions by screws f, going through it and each cleat and the part next adjacent yto the cleat, all being adapted and arranged substantially as shown in the drawings.

This ish-egg-hatchiug box is intended for use with trays placed in its several larger compartments, the eggs toV be hatched being arranged in such trays. The water passing into the trough at one end will ow from one ot' such compartments to the other' and upward through each series ot' trays and escape at the other end of the trough, which is notched, as shown at g, to allow the water to pass oi ata proper level.

I claim- The {ish-egg-hatching trough, substantially as described, composed ot' the notched end pieces, four connecting-bars, the series ot' notched transverse partitions, and the waterproof cloth or fabric and its fastening cleats and screws, arranged and adapted essentially as set forth.

LIVINGSTON STONE. Vitnesses:

GEORGE OLooTT, HERBERT W.`B0ND.
